Solution

The correct options are
B salt
C glucose
The essential substances in the filtrate are reabsorbed in the first half of the proximal convoluted tubule (early proximal tubule). These include glucose, amino acids, phosphate, lactate and citrate. 100% of the glucose and amino acids are reabsorbed but only 50% of the urea and 70% of the lactate is reabsorbed.
